Hack Squat: What the Hackenschmidt Squat Does and What Equipment You Need For It
Guided squat instead of free barbell: what the hack squat really trains, how it differs from the original Hackenschmidt squat, and when buying your own machine is worth it.
In short
A machine hack squat is a guided squat with a backrest and shoulder pads. It mainly trains the front of the thighs. The barbell variation behind the legs is a separate execution with different demands. When choosing equipment, check movement fit, assembled dimensions, loading and movement space, and floor load capacity. The new machines compared here are listed from CHF 2,590.
Definition
What is a hack squat?
A hack squat is a squat in which the torso rests against an inclined backrest and the weight is applied to a guided sled via shoulder pads. The exercise is named after the wrestler and strength athlete Georg Hackenschmidt, who performed it around 1900 with a barbell positioned behind his legs. This original form is still known today as the Hackenschmidt squat. However, when people search for “Hack Squat” or “Hacksquat” today, they almost always mean the machine, which you can find at our Plate-Loaded Category, so for the machines without weight stacks. Their principle is simple: a carriage that runs on inclined steel shafts and is loaded with weight plates on both sides. The track takes care of the balance, and you provide just the power. That is precisely what makes the movement predictable and the muscle stimulation very targeted, and it is the reason why the machine has been in every major weight room for decades.
Classification
Hack Squat or Barbell Squat?
The difference lies in who provides the balance. During a free squat, the core, back, and hips help stabilize the bar, and a noticeable portion of your strength goes into holding work. With the hack squat, the track dictates the path, your back rests against the pad, and almost the entire effort goes into the legs. This is not a replacement, but a supplement. The squat remains the better exercise for overall strength, core stability, and carryover into sports. The hack squat is the better choice for targeted thigh training and for high repetitions close to muscle failure without a shaky bar becoming a safety risk. Anyone who wants both but only has space for one is better off with a barbell and rack in almost all cases, because that also covers pressing, pulling, and deadlifting. Which rack fits your space is what the Buying guide for rigs and racks.
A backrest guides the torso but does not remove all load from the spine. Plate loads on different machines and free squats cannot be compared directly: sled angle, starting weight and mechanics differ. Choose the exercise to suit your training goal and execution.
Muscles and execution
Which muscles does the hack squat train?
The hack squat mainly uses the quadriceps, glutes and adductors. The knees and hips extend as you stand up; the backrest does not remove this movement. Foot position, depth and machine geometry change the execution. Start in a stable, comfortable position and change settings one at a time. For targeted knee flexion, a leg curl complements the training.
The sequence of movements in four steps:
- Shoulders firmly under the pads, back flat against the backrest, feet shoulder-width apart on the footplate.
- Release the safety lock, pick up the load, tighten your core.
- Lower under control through a range you can manage; keep heels and back against the intended supports.
- Push up through the entire sole of the foot without fully locking out the knees at the top.
Lifting heels or knee movement you cannot control are reasons to review the load, foot position and range of motion. A single sign is not enough to identify the cause with certainty.
Devices
Which hack squat machine fits in your space?
First compare the listed assembled dimensions and equipment weight. The shop states 150 x 145 x 95 cm and 115 kg for the RS-1033, and approximately 194 x 222 x 113 cm and 215 kg for the FM-1024F. Confirm the order of dimensions and usable footprint before ordering. Add side loading space, the full sled travel and access. The checked ATX combo page does not list dimensions or equipment weight, so its space savings cannot be compared reliably. Also clarify the delivery route, assembly and helpers required.

Check floor load capacity for the machine, user and planned loading. A floor protection mat can protect the surface but does not replace verification of the floor or supporting structure. The FM-1024F’s 1,200 kg figure is the shop’s stated equipment load rating, not a recommended load for your room. Also allow for suitable plates and their storage.
Price and Used Items
How much does a hack squat cost, new and used?
The ATX combo is listed at CHF 2,590; both new RealLeader machines were CHF 3,490 each when checked. Check product pages for current price, included items and stock. Used offers change regularly. Find the current selection in the Outlet. Before buying used equipment, check condition, guides, upholstery and safety catches.
For multiple machines, delivery access and layout planning also matter. For larger purchases, we advise studios, clubs and companies personally. The brand of a used machine currently available is not a permanent range commitment.
Honest assessment
Hack Squat without machine: three alternatives
For most home gyms, a hack squat machine is the wrong purchase. It can do exactly one family of exercises, takes up more floor space than a complete rack, and costs a multiple of it. If you train at home and have to choose between a hack squat and basic equipment, the basic equipment wins almost every time. Three ways still bring the appeal into your home anyway. First, the original form: the Hack squat with the barbell behind the legs and slightly elevated heels. It requires technique and grip strength, but doesn't cost an extra franc if the barbell and plates are already there. Second, a R-SERIES Power Rack for CHF 490.-, which also secures heavy squats alone with safety bars and additionally covers bench press and pull-ups. For the price of a single hack squat machine, you get a rack, barbell, and plates in the room, and the legs still get their work done.
Third, a belt squat attachment may suit a compatible rack. The load is applied through a belt around the pelvis. This differs from a hack squat machine and does not remove all load from the back. Check rack compatibility, belt, movement path and installation requirements together.

Frequently Asked Questions
Hack Squat: The most important answers
What is the difference between a hack squat and a Hackenschmidt squat?
This refers to the same movement in two variations. The Hack squat is the original version with the barbell behind the legs, named after Georg Hackenschmidt. Today, "Hack squat" usually refers to the machine where a guided sled handles the balance. The muscle stimulus is similar, but the barbell variation is more technically demanding.
Is the hack squat good for the knees?
The guided track eliminates lateral evasive movements, which makes the execution cleaner. At the same time, the fixed angle during very deep repetitions can place a lot of shear force on the knee joint. Foot placement, depth, and weight are crucial. If you already have knee issues, that question belongs with a physical therapist or doctor, not in a guide.
How much weight goes on a hack squat?
There is no universal starting number of plates per side. First check the unloaded sled and its safety catches according to the instructions. Increase the load only once you control the intended range. Angle, starting weight and mechanics prevent a direct comparison with your barbell squat.
Does a hack squat machine need a special floor?
The floor must support the machine, user and planned loading. Clarify this before installation, especially if the supporting structure is unknown. Depending on its material, a rubber mat protects the surface and reduces noise; it does not automatically increase load capacity.
Are weight plates included with the hack squat?
No. All plate-loaded machines are loaded separately; weight plates are not included in the scope of delivery. The weight horns are designed for Ø 50 mm as standard, and there is an adapter available for the ATX combo for Ø 30 mm. Factor in the weight plates, otherwise the machine will sit in the room unusable.
Can I do hack squats at home without a machine?
Yes, using the barbell variation. Pick up the bar from behind your legs, heels slightly elevated on a plate or wedge board, then bend and extend in a controlled manner. The stimulus on the front of the thighs is close to that of the machine, but the demands on grip strength and mobility are significantly higher.
What is a reverse hack squat?
Reverse hack squat means performing the movement facing the machine. Not every hack squat machine is designed for this. Use that position only if the instructions, supports and safety catches explicitly permit it. Facing the other way alone does not establish suitable or safe use.
